This invention relates to new and useful improvements in mop wringersand the primary feature of the present invention is to provide a deviceof the character referred tothat is adapted towring a mop free of asurplus of water by a mop squeezing mechanism.

Another important feature of the present invention is to provide a mopwringer in which a pair of opposed perforated jaw members are connectedat their lower ends by spring means so that the lower ends spread apartunder tension as the mop head is extended downwardly between the jawmembers and the upper portions of said jaw members pivot inwardlyagainst the mop head squeezing water from the mop head.

A further feature of the present invention is to provide a mop wringercomposed of a pair of opposing jaw member that are so shaped as toembrace a mop head and having slots to aid in the removal of watertherefrom.

A still further feature of the present invention is to provide a deviceof the class described that is simple and practical in construction,reliable in use, relatively inexpensive to manufacture and otherwisewell adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view of the improved mop wringer withparts broken away and shown in section;

Figure 2 is a vertical sectional view taken on the line 2-2 thereof;

Figure 3 is a perspective view of the mop wringer with parts broken awayand shown in section;

Figure 4. is a longitudinal vertical sectional view of the deviceinserted within a bucket (shown in section) and showing a mop applied tothe device and Figure 5 is a bottom plan view of Figure 1.

Referring now to the drawings in detail. wherein for the purpose of ilustration I have disclosed a preferred embodiment of the presentinvention, the numeral 5 represents a cylindrical casing open at bothends and having an annular outwardly inclined flanged portion 6 at itsupper edge for a purpose which will presently appear.

The wringer is preferably comprised of two mop squeezing jaw members Iand 8 which are connected by a coil spring 9 having terminal 6 Claims.(Cl. 15-261) 2 loops l0 engaged by hooks ll projecting out wardly fromthe lower rear portions of the memhers I and 8.

The side walls [2 of members 1 and 8 taper toward the upper ends of themembers I and 8. Pivots or trunnions l3 are provided on the lower sidesof members 7 and 8 and are journaled for rotation in openings [4reinforced by rings 14a at the lower end of the casing 5.

The jaw members 1 and 8 are provided with any suitable number ofelongated slotsor open-v ings [5 through which the excess moisture in amop head l6 may pass.

In use of the device the casing 5 is inserted into a conventional bucketor the like I! with the flanged portion 6 of the casing bearing againstthe upper edge of the bucket as more clearly shown in Figure 4.

As the mop head I6 is pressed downwardly on the lower walls of members 1and 8 the upper portions of the members are pivoted toward each other ontrunnions I3 so that the opposed side edges l2 of said members aresubstantially parallel and the jaw members clamp against the mop headcausing excess water to be squeezed from the mop head. The excess waterwill pass through openings [5 and also through the lower end of theinner casing 5 into the bucket.

When the members are in their mop squeezing position tension is placedon spring 9 so that when the mop head is removed from the device the jawmembers will pivot back to a normal position with their upper portionsspaced apart sufficiently to permit removal of the mop from the jawmembers.

In view of the foregoing description "taken in conjunction with theaccompanying drawings it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is: accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain chan es fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.

I claim:

1. A mop wringer comprising a pair of coacting jaw members, each of saidjaw members including upper and lower portions, the lower portion ofeach jaw member including a lower wall, the lower walls of the jawmembers extending toward each other, a casing embracing said jawmembers, pivot means securing the lower portions of said jaw members tothe casing for movement of the upper portions of said jaw members towardand away from each other, said pivot means being so located as to permita reduction in the volume defined between the adjacent surfaces of themembers as the upper portions of the members are moved together and acoil spring underlying said lower walls and terminally attached to thelower portions of said jaw members yieldingly urging the lower portionsof said jaw members toward each other and also yieldingly urging theupper portions of said jaw members apart.

2. A mop wringer comprising a pair of coact ingrjaw members, each ofsaid jaw members including an upper portion and a lower portion, the

lower portion of each jaw member including a lower wall, the lower wallsof the jaw members extending toward each other, a pair ofcoaxial member,and spring means connecting thelower portionsof said jaw members andyieldingly urge ing the lower portions of said jaw members to gether andalso yieldingly urging the upper portions ofrsaid jaw members apart;

3; A mop wringer comprising a pair of coasting, jaw members, each ofsaid jaw members including an upper portion and a lower portion, thelower portion or" each jaw member including a lower wall, the lowerwalls of the jaw members extending toward each other, a pair of coaxialpivots projecting from each of jaw and disposed relatively close to thelower walls of said jaw memberslsaid pivots being so located astopermita reduction in the volume defined between the adjacent surfaces of themembers as the upper portions of the members are moved together, acasing surrounding the jaw members and having openings therein receivingsaid pivots, the pivots of one of said jaw members being spaced parallelto the pivots of the other jaw member, and spring means connecting'thelower portions of said jaw members and yieldingly urging the lowerportions of said jaw members together and also'yie'ldingly urging theupper portions of said jaw members apart, each of said jaw members beingelongated and transversely curved and including substantially triangularside pieces integrally formed with said members and said lower walls.

'4, The combination of claim 2 wherein said spring means includes anelongated resilient member having terminal loops, and hooks on the 4lower portions of said jaw members receiving said loops, said resilientmember underlying said lower walls.

5. A mop wringer comprising a casing open at its top and bottom, a pairof cooperative mop squeezing jaw members having drainage openings, saidjaw members having opposed side walls, each of said side walls taperingtoward the upper end of their respective jaw members to provide a'mopreceiving openin between said jaw members, said jaw members includinglower walls extending toward each other, pivot means mounting the lowerportions of said jaw members to the casing for movement of the upperportions of the jaw members toward and away from 'each'other, said pivotmeans being so located as toreduce the volume defined between theadjacent surfaces of the members as the upper portions of the membersare moved to ether, and spring means between said members under- 'ly-ingsaid lower walls andyieldingly urging the lower. walls of the jawmembers toward each other and the upper portions of the jaw membersapart.

6. A mop wringer comprising a casing open at its top and bottom, apairof cooperative mop squeezing jaw members having drainage openings,said jaw members having opposed side walls, each of said side wallstapering toward the upper'end-of their respective jaw members to providea mop receiving opening between said jaw members, said jaw membersincluding lower walls extending toward each other, pivot means mountingthe lower portions of said jaw members to'the casing for movement of theupper portions of the jaw members toward and away from I REFERENCESCITED Thefollowing references are of record in the file of this patent:
